4. Come and Get Your Love
Guardians of the Galaxy
Screenwriting is hard. And creating memorable scenes is harder. But you know what's really hard? Making an audience instantly love a character.
But holy hell does Guardians of the Galaxy do exactly that. After the flashback prologue, we are introduced to Peter Quill AKA Star-Lord as an adult. And after Indiana Jones-ing his way into some sort of ancient tomb, he pops off his space helmet, clicks in his Walkman, and plays Redbone's "Come and get Your Love" and holy heck, a beloved film franchise was born.
You could trace most filmgoers love for the Guardians to that specific exact moment. It is such a defined character introduction you could use it as a masterclass in screenwriting. You want to know what this character is about? Here you go.
In one scene you get the tone of the movie, the ethos of the main character, the aesthetics of the film, so much beautiful work all done in a scene that is also funny as all hell.
